A structure including a collapsible and retractable frame to fit or go inside a plastic bag of a type used for gathering leaves, weeds and/or clippings of grass, bulky materials such as garbage or trash, paper towels or other disposable items to be packaged in the plastic bag. The frame has four upright corner or side rods pivotally interconnected by double hinges relative to four upper rod members and four intermediate rod members without any bottom interconnections. Rubber tips are fitted to lower free ends of each of the four upright corner or side rods. A semicircular handle has opposite ends thereof twisted pivotally to a pair of parallel upper rod members so that the frame can be fitted and unfolded in a plastic bag as well as removed therefrom and folded flat for storage purposes. Clips are used to hold the plastic bag to the four upper rod members. The rubber tips at the lower ends of the corner or side rods prevent tearing and/or possible puncturing of the plastic bag held open in a squared-rectangular configuration subject to closing of the open top of the bag by plastic-coated wire twist or string or rope to hold disposable materials in the plastic bag after unobstructed removal and retraction of the frame structure therefrom.
